Ever since Apple announced that Siri would be exclusive to the iPhone 4S, hackers have been chomping at the bit to port the AI voice assistant to older devices. The jailbreak community has released several hacks, including one, Spire, that is the product of some of the most notable developers on the scene.

If a recent report is accurate, however, the whole process may have been sitting under our noses for months. An iPod touch owner supposedly set up his device by restoring from a backup he had made from an iPhone 4S. After restoring the device, he was shocked to see that it had Siri installed.

Any Siri port is going to need live validation tokens from an iPhone 4S in order to connect to Apple’s servers. Apple added the extra layer of security, which needs a new 4S token every day or two, to make it more difficult for hackers to port Siri. It has worked quite well, as it won’t likely ever be possible for users to simply download a Cydia jailbreak app and get full Siri functionality.

Though the backup/restore method isn’t immune to Apple’s protection, apparently Siri’s dictation does work. Attempts to converse with Siri bring up error messages, but dictation works like a charm. If this story is legit, it will offer a simple way to get dictation added to any iOS device with a microphone.

That, however, is a huge “if.” Though iOS devices can indeed restore backups from other devices, it sounds unlikely that Siri would be part of any backup — at least without explicit safeguards in place to prevent restores on different devices. The fact that the user’s iPod touch is jailbroken only adds to the suspicious circumstances.

For now, we’d say this is a curiosity-inspiring story, but it could be 100% phony. Restoring a backup from a different device can lead to problems, so we wouldn’t advise you to try this at home.
